Web19 de mar. de 2004 · Likelihood ratio tests were used for verifying hypotheses on the variance parameters and on the random effects. These test statistics tend, however, to be quite ‘anticonservative’ when testing for fixed effects terms, and conditional t -tests and F -tests as described in Pinheiro and Bates ( 2000 ), section 2.4.2, were used instead. http://evomics.org/resources/software/molecular-evolution-software/modeltest/

WebNumerous other tests can be viewed as likelihood-ratio tests or approximations thereof. The asymptotic distribution of the log-likelihood ratio, considered as a test statistic, is given by Wilks' theorem. The likelihood ratio is also of central importance in Bayesian inference, where it is known as the Bayes factor, and is used in Bayes' rule.
